T.H.E. Widower distortion will literally take your head off with its high gain, high sustain amp-like distortion sound. 

Sporting an active boost/cut 2 band EQ. The unique character of this pedal is in part due to the cmos input opamps utilized for the three gain stage design. This provides a different tonal quality than your standard JFET input opamp, such as the TL072. The Edge control gives you the ability to shape your waveform before it enters the gain section giving you a wider tonal palette of distortion from "British" to "USA" style voicing allowing you to get a nice crunch tone or a high gain distortion.

This build can be run as a preamp into an effects return or into other pedals/amp. My preference is as a preamp being boosted by another pedal.
